What is the mechanism whereby radio waves could accurately read brain impulses?

think about an mp3 player. audio to digital conversion then digital to digital (HDTV). there's a science (psychology) behind how the brain interprets the sounds it hears together with what your eyes and central nervious system tells your brain (digital conversion).

and the brain is basically a magnet just like the one sitting in your computer. ready to be reprogrammed or taken for a ride through your memories (with your feelings/emotions).

for all those who don't believe your dreams can be manipulated, consider hypnosis. lights and radiowaves elliciting desired feelings/emotions to control behaviors.

now consider your brain with the possibility of it being 'partitioned' just like a computer. i recently read of a virus that copies your operating system, creates an invisible partition on your computer, and then takes total control of your operating system and your computer.
